CARLINE.

Application filed November 5, 1919.

To all ywhom t may concern:

Be it known that I, JAMES J. MCCAR'ri-IY, a citizen of the United lStates, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Carlines, of which the iollowing is a speciiication.

The invention relates to carlines more particularly designed for use in freight car rootl frames, and has for an object to combine the advantages of a double-Y form of cai-line, in having wide bases of attachment to the side frame members or side plates, with the advantages oi' a straight carline in more directly and stiflly uniting said frame members; with a further result of making the carline as a Whole stronger for the resistance of all vertical, horizontal and torsional strains. These results are attained by a peculiar shaping of a single steel bar of T-section.

With such objects in View, as well as other advantages which may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constiuting the same may be varied in proportions and arrangement without departing from the nature and scope of the invention.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose oi explanation, have been made the subject of illustration. In the said drawings Fig. 1 is a plan view of a portion of a car roo'l frame comprising a carline embodying the invention.

Fig. 2 is a vertical transverse section of the roof, showing said frame and the sheathing in section and the carline in elevation.

Fig. 3 is a perspective view of a portion of one end of the carline.

Referring to the drawings, l indicates the side plates of the roof frame, 2 the ridge pole, 3 the purlins, 4; the top sheathing, 5 the side sheathing, and 6 the side fascia'.

A indicates the 'carline consisting of a single steel bar of T-shape in cross section, arranged to have horizontal top iianges a and a vertical, central depending i'lange l).

sei-iai No. 335,889.

At its apex the carline is horizontal for a short distance as shown at 7 and at this point the ridge pole is supported by the iianges a and secured by a bolt 8 passing down through one of said flanges. At each side of the part 7 the carline declines towards the side plates, and each end of the carline is split into three branches (Fig. l).

The two lines of splitting or shearing are along the sides of the vertical flange l), and said flange entends thence in the Jform of plain bars 9 to the side plates where they are bent to form feet 11 which brace against the inner sides of the side plates, to which they are secured by bolts 10.

The two top flanges a of the carline are bent away from the bars 9 into diagonal positions, forming bracing elements and eX- tend in the form of plain fiat bars 12 to and across the side plates, and are formed with depending hooks 18 which engage the outer sides of the side plates. Securing bolts 14 pass through said hooks and the side plates.

The purlins are secured to the flanges a of the carline by bolts 15, and Where the outer purlins rest on the bars l2 they are preferably secured by two of such bolts (Fig. 1), thereby maintaining the proper positions of said bars.

By the above described construction of a single bar I provide Jfor bracing the carline on the side frame members at four widely separated points and also tie the side members together at intermediate points in line with the body and axis of the carline.

TWhat is claimed ism l. A carline for freight car roofs and the like, consisting of a single steel bar oi` T- section, split at the ends along its depending iiange, said liange being maintained as a bracing bar in the vertical plane of the body of the carline, and the separated side lianges being inclined away Yfrom said bracing bar to diagonal positions and adapted for connection with the roof frame at widely separated points at both sides of said plane.

2. A carline consisting oi a single steel bar of T-section, having its central iiange arranged as a bracing bar adapted to extend from side to side of the roof frame, and having its side flanges united with the central lange along the middle part of the carline, the end portions of said side flanges being bent into diagonal positions at both sides oi said central flange ior connection with the roof frame at widely separated points.

3. A carline for freight car roofs and the like, formed with an apex for the support of the ridge pole, declining thence to each side plate, and each of its ends formed with diagonal branches having means for engagement with the outer sides of the side plates, and with an intermediate bar, said intermediate bar extending continuously from side plate to side plate and having at its ends means for engaging against the inner faces of the side plates.

t. A carline for freight car roofs and the like, formed with an apenv for the support of the ridge pole, declining thence to each side plate, and each of its ends formed with diagonal branches having means for engagement with the side plates, and formed with an intermediate bar, said intermediate bar extending continuously from side plate to side plate.

5. A carline having a depending flange, and having at each end bracing elements which are integral with portions of said depending flange and are bent away from said flange in forward and rearward directions, respectively, leaving said depending flange intermediate said. bracing elements, said bracing elements being adapted to be secured to the side plates.

G. A carline having a depending flange, and having at each end bracing elements which are integral with portions of said depending flange and are bent away from said flange in forward and rearward directions, respectively, said bracing elements at each end of the carline having means for engaging against one side of the side-plate, and

plate at a point between said bracing elements.

7. A carline having a depending flange, and having at each end bracing elements which are integral with portions of said depending flange and are bent away from said flange in forward and rearward directions, respectively, said bracing elements at each end of the carline having means for engaging against the enter side of the sideplate, and said depending flange having means for engaging against the inner side of the side plate at a point between said bracing elements.

8. A carline having a niain body extending past the ridge of the roof and towards each side plate and having its end portions divided and separated into a plurality of bracing elements adapted to engage the side plates of the roof, certain of said bracing elements having means for engaging against the inner sides of the side plates and other of said bracing elements having means for engaging against the enter sides of said side plates.

9. A carline having a vertical flange, and horizontal flanges integral therewith, and having at each end bracing elements which are integral with portions of said vertical flange and are bent away from said vertical flange in forward and rearward directions, respectively, to engage side plates, said vertical flange continning to engage side plates.

ln testimony whereof l have hereunto set my hand.
